Abstract
摘要 |
Closed string field theory is governed by an L-infinity algebra of interactions, with quantum action satisfying B-V master equation. We will describe a B-twisted version of topological closed string field theory generalizing the Kodaira-Spencer gauge theory. As an example, we explain a complete solution of quantum B-V master equation on elliptic curves in terms of chiral algebras via an evolution of integrable system. This leads to a simple description of the corresponding higher genus mirror symmetry. If time permits, we will also describe a conjectured relation of it with twisted supergravity.
